Ingredients You’ll Need
- 8 oz medium pasta shells: This is the foundation of the dish. Shells are perfect for holding the sauce and cheese.
- 2 teaspoons olive oil: A flavorful fat that helps sauté the shallots and garlic.
- 3 garlic cloves, minced: Adds a fragrant aroma and depth to the sauce.
- ½ cup shallots, minced: If you don’t have shallots, finely chopped onions work well too, providing sweetness.
- 12 oz Italian sausage, removed from casing: This gives a hearty flavor; consider using turkey sausage for a leaner option.
- 28 oz can crushed tomatoes: The star ingredient of the sauce; choose high-quality tomatoes for the best flavor.
- 1 tablespoon tomato paste: This deepens the tomato flavor and adds richness.
- 1 ½ tablespoons granulated sugar: Helps balance the acidity of the tomatoes; can substitute with honey.
- ½ teaspoon kosher salt: Essential for enhancing all the flavors; adjust to taste.
- ½ teaspoon freshly ground black pepper: Adds a hint of spice; feel free to increase for a bolder bite.
- Pinch red pepper flakes (optional): A little heat goes a long way—add more if you like it spicy.
- ¾ cup low-fat (2%) cottage cheese, small curds: Offers creaminess without being overly heavy.
- 6 oz mozzarella cheese, cut into ½-inch cubes: Melts perfectly and provides wonderful texture.
- 1 cup shredded mozzarella cheese: This is for topping, creating that irresistible cheesy crust.
- Chopped Italian parsley, for garnish: Fresh herbs will brighten up the dish and add a nice color contrast.
How to Make Baked Penne | Cheesy Oven-Baked Pasta Casserole
Cook pasta: Begin by cooking the 8 oz medium pasta shells according to the package directions until they are al dente. This usually takes about 8-10 minutes. Drain them and set aside to cool, ensuring they don’t stick together.
Make sauce: In a medium pot over medium heat, warm 2 teaspoons of olive oil. Add 3 minced garlic cloves and ½ cup minced shallots, stirring often for about 2-3 minutes until softened and fragrant. Next, introduce the 12 oz Italian sausage, breaking it into small pieces as it browns. Drain any excess fat, making sure to keep that delicious flavor in the pot.
Simmer: To the browned sausage, add a 28 oz can of crushed tomatoes, 1 tablespoon of tomato paste, 1 ½ tablespoons granulated sugar, ½ teaspoon kosher salt, ½ teaspoon freshly ground black pepper, and a pinch of red pepper flakes if you like a little heat. Stir everything together, bring to a boil, then reduce to a simmer. Let it cook for about 10-15 minutes; taste it along the way to adjust the seasoning as needed. Allow the sauce to cool for 15 minutes before proceeding.
Assemble: Preheat your oven to 350°F. In a large bowl, combine the cooled pasta with the cooled sauce, ¾ cup cottage cheese, and the 6 oz of mozzarella cheese cut into ½-inch cubes. Toss everything well to coat. Transfer the mixture to a 9×13-inch baking dish. Don’t forget to top it with 1 cup of shredded mozzarella for that irresistible cheesy crust!
Bake: Place the dish in the preheated oven and bake for about 20 minutes until the cheese is melted and bubbly. For an even more appealing finish, broil for 30-45 seconds until the top is beautifully golden. Let it stand for about 5-8 minutes before serving, garnished with fresh chopped parsley for a bit of color and brightness.

Storing & Reheating
Leftovers can be safely stored at room temperature for up to 2 hours. For longer storage, transfer to an airtight container and refrigerate for up to 3 days. You can also freeze the baked penne for up to 3 months—just make sure to wrap it tightly. When rewarming, the best method is to heat in the oven at 350°F for about 15-20 minutes, covered with foil. The textures may change slightly, but adding a dash of olive oil before reheating can refresh the dish beautifully.
Chef’s Helpful Tips
- Avoid overcooking the pasta; it will continue to cook while baking in the oven.
- Let your sausage cool before combining with the other ingredients to prevent curdling the cottage cheese.
- If using gluten-free pasta, check the cooking instructions as they may vary from traditional pasta.
- Consider adding some sautéed vegetables, such as zucchini or spinach, for more nutrition and flavor.
- Prepare the sauce and assemble it a day ahead, then simply bake it when you’re ready to dig in.
